Ven using Thunder at the Castle of Dreams

Thunder (サンダー, Sandā), Thundara (サンダラ, Sandara), and Thundaga (サンダガ, Sandaga) magic are offensive spells Sora, Donald, and other characters and enemies associated with the element of lightning.

Uses

Kingdom Hearts Birth by Sleep

Thunder magic in Kingdom Hearts Birth By Sleep creates a ring of lightning around the caster. Any enemies within the ring are struck with lightning from above. The ring's circumference expands on the higher levels of the spell.

Kingdom Hearts

In Kingdom Hearts, Thunder was a more powerful and also more costly spell than Fire or Blizzard, summoning a barrage of lightning bolts from above to strike the surrounding enemies at the 1 MP bar.

Characters who cast Thunder magic in Kingdom Hearts:

• Sora
• Donald
• Jack Skellington
• Ariel
• Genie

Kingdom Hearts: Chain of Memories

In Kingdom Hearts: Chain of Memories, Thunder appears as a magic card that can be used in the following sleights:

• Thundara
• Thundaga
• Thunder Raid
• Freeze (Re:CoM only)

Keyblades are sometimes given elemental properties in this game. Thunder-elemental keyblades appearing in this game are as follows:

• Spellbinder
• Photon Debugger (Kingdom Hearts RE: Chain of Memories only)

Kingdom Hearts II

In Kingdom Hearts II, Thunder is approximately equal to the other base elemental spells Fire and Blizzard in power. The spell summons a single lightning bolt to strike an enemy and an area-of-effect that is expanded with each upgrade.

A new ability, Thunder Boost, appearing in Kingdom Hearts II increases the amount of damage caused by lightning-elemental spells. Although it may be learned by levelling, it is also a passive ability acquired when equipping the Photon Debugger keyblade.

Characters who cast Thunder magic in Kingdom Hearts II:

• Sora
• Donald
• Jack Skellington
• Tron

Kingdom Hearts 358/2 Days

In Kingdom Hearts 358/2 Days, Thunder sends out a straight line of lightning before the caster. Thundara resembles Thunder magic as it appears in Kingdom Hearts, in which lightning strikes randomly around the caster for a brief period of time. Thundaga invokes a single, enormous bolt of lightning to strike the target.
